are hashrates for total rig power? say if I have two rigs 800 kH/s each, which network should I stick?
If the two rigs are mining to the same address, then combined power. I'd probably go for 2nd network.
Are you sure the node will adjust difficulty to the hashrate? If not, both miners will get diff too high and will miss a shareblock.
I'm not sure p2pool nodes use diff adjustment extensively.
No. They do not. If you need vardiff (auto-diff adjustment), try one of the Proxypools which feeds into P2Pool. I have a Proxypool running at
. You may like to give it a try.
